A laboratory study was performed by exposing seven candidate heat exchanger alloys to simulated 2 (sCO2) Brayton power cycles. The alloys, consisting of fineirtriaitilcly s 3te.6e%ls ,O austenitic stainless steels, and nickel-base alloys, were exposed to impure CO2 containing 2 and 5.3% H2O at a constant pressure of 200 bar.

Selected Fe- and Ni-based alloys and superalloys have been exposed in 99.995% supercritical carbon dioxide for 500 hours at 750°C and 200 bar. Post exposure examination provided information on corrosion rates, microstructural evolution and the carbon concentration in the exposed materials.
Precipitation hardened (PH) nickel-base alloys are frequently used as engineering materials in the Oil & Gas industry. They excel because of their outstanding combination of strength, toughness, and corrosion resistance. In that regard, alloy N07725 is of high interest as it offers better corrosion resistance than the widely used N07718, while also offering better high temperature strength than solid-solution nickel-base alloys.
Recent results of sour gas and hydrogen embrittlement testing of CW N07022 alloy will be presented. The test results of CW N07022 alloy will demonstrate that it offers superior properties to precipitation-strengthened Ni-base alloys for demanding oil and gas applications.
